Mustard relative native to mountains of central and southern Europe, Turkey. Gray leaves (sometimes variegated white) form a spreading evergreen mound 8–12 in. high; dwarf forms are half as tall. Dense clusters of single or double, tiny, yellow to apricot flowers cover the plant in spring and early summer.
Use as foreground plant in borders, in rock gardens, atop walls; plant about 1 1/2 ft. apart. Poor soils or moderately fertile ones suit the plant perfectly as long as drainage is good. Shear lightly (don’t cut back stems by more than half ) right after bloom. Generally hardy but may be killed in extremely cold winters. Self-sows readily.'Goldkugel'
